Lake nutrient partition control technique

Abstract

The invention discloses a lake nutrient partition control technique, which relates to the lake eutrophication control and management field, and is characterized by comprising the following steps that: a partition index is preferentially selected from an optical index collection so as to carry out the lake nutrient primary ecological partition and to carry out the lake nutrient secondary ecological partition, ecological efficiency of the nutrient is adopted as an index to verify the partition result, the partition result is assessed, the partition result is determined after being adjusted, and a corresponding lake nutrient control measure is taken for different partitions. A partition index system is established according to factors influencing the lake eutrophication, the ecological partition is realized through quantitative and quantitative analysis, and then the ecological partition is verified, assessed and adjusted to enhance the objectivity, adaptability and feasibility of the partition result. Due to the adoption of the technique, a lake nutrient ecological partition technique system is established, so vigorous technical support can be provided to the ecological partition in China.

Description

technical field [0001] The invention relates to the field of lake eutrophication control and management, in particular to a technical method for lake nutrient partition control. Background technique [0002] Eutrophication of lakes has become a common phenomenon in the world today, and 30% to 40% of lakes in the world have been affected by eutrophication to varying degrees. In recent years, the trend of eutrophication in lakes in my country has been severe. In the past 40 years, the eutrophication area of ​​lakes in China has increased by about 60 times. The problem of eutrophication in lakes seriously restricts the sustainable development of society. According to the advanced experience of some developed countries in the prevention and management of lake eutrophication, actively carrying out work such as lake ecological zoning, nutrient benchmarks and eutrophication control standards has become an important development trend of current lake eutrophication control and managem...
